Summer Review Sheets — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A pool party needs 11 pizzas at $9 each. The total cost is $99 .
Multiply 11 pizzas times $9 each: 11 times 9 equals $99.
2. An angle that measures exactly 90 degrees is called a right angle.
A right angle measures exactly 90 degrees and looks like the corner of a square or a book.
3. A camp divides 192 trail mix bags among 8 groups. Each group receives 24 bags.
192 divided by 8 equals 24. You can check: 8 times 24 = 192.
4. Two fractions that name the same amount are called equivalent fractions.
Equivalent fractions represent the same value, like 12 and 24. Even though they use different numbers, they name the same amount.
5. A lifeguard counts 12 rows of 9 chairs by the pool. There are 108 chairs total.
Multiply 12 rows times 9 chairs per row: 12 times 9 equals 108 chairs.
6. A shape with four sides and four right angles is called a rectangle.
A rectangle has exactly four sides and four right angles (90-degree corners). Squares are special rectangles too.
7. Three families spend $65 each on beach passes. Together they spend $195 .
Multiply 3 times $65: 3 times 60 is 180, plus 3 times 5 is 15, so 180 + 15 = $195.
8. A line segment has two endpoints that mark where it begins and ends.
Endpoints are the two dots at each end of a line segment that show where it starts and stops. Without endpoints, the line would go on forever.
9. A water park sells 288 tickets in 6 hours. It sells 48 tickets per hour.
288 divided by 6 equals 48. You can check: 6 times 48 = 288.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
acute angle
→ measures less than 90 degrees
measures exactly 90 degrees
obtuse angle
→ measures more than 90 but less than 180 degrees
measures exactly 180 degrees
right angle
→ measures exactly 90 degrees
measures less than 90 degrees
straight angle
→ measures exactly 180 degrees
measures more than 90 but less than 180 degrees
Correct matches: acute angle → measures less than 90 degrees; obtuse angle → measures more than 90 but less than 180 degrees; right angle → measures exactly 90 degrees; straight angle → measures exactly 180 degrees.
